arraaarus non nrnncrmernn vuncnmzine ornm'nons AND GENERAL nnrnins Be ,it known that. I, WILFRID lan managing "director, have invented a certain new andfusefu'l improyed apparatus for efi'ecting the vulcanizing operations and general repairs connection {with the tires of motor road-'vehicles and ,7 the, like, (for which I have applied for Letters-Patent in Great Britain, Patent} No. 2%,836, dated. November 9, 1907,) of whichthe following is a specification.

sheets of drawings upon which I have illust ra-ted the nature of my said invention.

' Figure'l is a sectional side elevation of a vulcanizing apparatus constructed accord- I to the present invention. Fig.2 is a sectionalend view showing the air conduit the section being on plane'tX Y ofFig. 1. Fig. 3 is a front perspective view of the vulcanizer shown by Fig. 1. Fig. 4 shows in perspective theunderside ofone of the detachable side surfaces for vul'canizing on .1111 the embodiment a this invention by Bunsen-burners C provided in the bottom ofthe casing A. The partitions inintegral with the casing A but are advantageously constructed of detachable lates b 6 secured together and to the casing A by. any suitable means such {as screws 1b", the bosses b,'serv1ng as distance'pieces, while suitable provision is made to prevent downwarddisplaoement of thepartitions.

The part of the roof or wall of the apparatus forming the channel mold dfor the treatment'of outer covers is detachably connected to the body .and is interchangeable with channel molds of difierent dimensions covers requiring treatment and the channel 'molds are also interchangeable with flat plateso'r molds for the vulcanization of inner tubes, the interchangeablemembers beingf preferably placedin correct relation to the casingwithout any direct connection.

" The side molds or surfaces 6 for the process of vul canization' on the flat arelikewise interchangeable and maybe "adapted to imclosing the cold air conduits b may be made i I part therequisite outer configuration to the finished repair which in the case of an outer I I the tread. To accommodate the valve of'the tube, a

cover constitutes the design of sjuita'ble hollow downward I r'ojection may rovided on the side mol s e. The side mods e are preferably constructed, as shown in Fig.4, w1th portions 6- adapted to retain to a ccormuodate the various sizes of tire the molds in position in the casing, a suitable lug e being provided to enable a thermometer to be placed therein.

The screw clamping members it are mounted upon extensions or fixed partsa of the stationarybody B and are thereby adapted for use in connection with the various interchangeable molds which may be employed and they are fitted for pivotal displacement by which means the pressure may be applied to such portion of the job as may be desired with facility.

The thermometers are adapted to pass through the casing into the heating chambers at the sides of the apparatus and they are preferably arranged in such a manner as to provide for the positioning of the bulb at or near the center of the chamber, thereby effecting a substantially correct and average indication of the temperature, while if desired provisionma-y be made for the pivotal movement of the thermometer with the accompanying circumferential displacement of the bulb within the chamber to thereby afford a more exact determination of the internal temperature. In the case of the channel mold d, a lug cl is located on the lower side of the mold and may advantageously be at an incline so as to allow of the application of a straight thermometer, while a thermometer bent at right angles may be used with the side molds e by the medium of the lug 0 Such lugs e d extending into the interior of the heating chamber give as aforesaid a more accurate indication of the temperature therein.

With such an apparatus it is possible to effect a more efiicient vulcanization of the repair, the operation being at the same time facilitated, and notwithstanding this provision is made for themore perfect vulcanization of covered articles by means of a single appliance.

Having now described my invention, I declare that what I claim is 1. A vulcanizing apparatus comprising in combination, a base, an elongated rectangular casing mounted on said base and having openings registering with the tops of said air insulating chambers, and a burner near the bottom of each heating chamber, said casing having air ingress apertures opening to the heating chambers adjacent the burners, and said partition walls having air ingress apertures opening to the air chambers at points adjacent the air ingress apertures of said casing whereby the air supplied to said air chambers is slightly preheated by its passage through the heating chambers and adjacent the burners thereof, substantially as. and for the purposes set forth.

2. A vulcanizing apparatus comprising in combination, a casing structure having a top adapted for vulcanizing tires or the like, a partition dividing the interior of said casing into chambers, said partition comprising walls spaced apart from each other and forming an air passage chamber, the top of said casing structure having an air egress opening for said passage and the upper end of the partition wall being spaced apart from the top of said casing structure for the discharge of air from said heating chamber to said egress of said air passage, a burner near the bottom of each heating chamber, said casing and structure having air ingress openings for said chambers adjacent said burners, and said partitions having ingress openings near said burner and opening to said heating chambers for passage of air therethrough toward and between said partition walls, substantially as described.

3. A gang vulcanizing apparatuscomprising in combination, a casing structure provided with vulcanizing elements, partition Walls dividing said casing structure into heating compartments for heating said ele ments and into air passage heat insulating 100 chambers disposed between and partitioning oil the heating compartments from each other, each heating compartment having means for heating the same, said air passage chambers having air ingress and air egress 10 5 openings for passage of air through said chambers, and said partition walls being formed of heat conducting material and serving to conduct heat from said compartments to said chambers to maintain a draft of air in the latter and prevent transmission of heat or cold from one compartment to another, substantially as described.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
